Abstract
This report gives the optical design and analysis of a two-element IR Offner-type null corrector for ground aspheric surface. The optical system assumes an interferometer that consists of a point source, a 85 mm diameter relay lens, and a 20 mm diameter field lens. The aberration of the IR null correctors is PV0.0076λ.An optical test for measuring the null correctors is presented in this paper.
